[Comparison of radial immunodiffusion and laser nephelometry for the determination of pregnancy specific beta 1-SP1-glycoprotein in plasma].
Concentrations of pregnancy-specific beta 1-glycoprotein were assayed in 137 plasmas by radial immunodiffusion and laser nephelometry. The two methods were evaluated in parallel. A good correlation factor was founded for SP1 values above 60 mg/l. Although the sensitivity of both methods at low concentrations remained unsatisfactory, that of laser nephelometry was superior and therefore to be preferred.
